Many data import platforms require uploading CSV files, but business personnel often have multiple Excel spreadsheets on hand. If you open each xlsx or xls file one by one and save as CSV, the operation is repetitive and prone to omissions. This article introduces a batch processing method more suitable for office scenarios: use the Excel to CSV conversion feature in HeSoft Doc Batch Tool , first select the corresponding task in the Excel tools category, then add files or import files from a folder to batch-add the spreadsheets to be processed, and finally set the save location according to the wizard and start the conversion.
In corporate office tasks, "Save Excel as CSV" may seem like a minor requirement, but when the number of files increases, it quickly turns into inefficient, repetitive labor. For example, a project folder might contain multiple xlsx spreadsheets such as sales data, product lists, order records, meeting minutes, customer information, and employee salaries, all of which need to be converted to CSV format before system launch. Using the traditional method, you have to open each Excel file individually, click "Save As," select the CSV format, and confirm saving. The more files you have, the easier it is to miss one or save the result to the wrong location.
The solution provided in this article is to use the batch processing capability within office software to complete the format conversion of multiple Excel spreadsheets to CSV in one go. The software name in the screenshot is HeSoft Doc Batch Tool , which is designed for document batch processing scenarios and is suitable for converting, organizing, renaming, or performing other batch tasks on large numbers of files. The following sections will focus on the question "How to save multiple Excel spreadsheets as CSV at once," detailing applicable scenarios, the before-and-after effects of conversion, and specific operational steps.
Applicable Scenarios: Which Office Tasks is Batch Saving as CSV Suitable For
The advantage of the CSV format lies in its universality, light weight, and ease of reading. Many systems do not directly accept xlsx files but can read CSV files; many data processing programs also prefer the plain text structure of CSV. Therefore, batch Excel-to-CSV conversion frequently appears in data import, report exchange, cross-system migration, and automated processing workflows.
For example, sales personnel receive multiple regional Excel sales sheets weekly and need to uniformly convert them to CSV for submission to a data analysis platform; project managers want to sort task files like Project Tasks.xlsx for batch import into a project management system; customer service teams collect Feedback Survey.xlsx forms that need conversion to csv for statistical analysis; operations personnel maintain Product List.xlsx product lists and Order Records.xlsx order records, needing to convert these spreadsheets into a system-recognizable CSV format.
If there are only one or two files, manually saving as CSV is not a big problem. However, when the number of files reaches 8, 20, or even more, batch processing tools significantly boost efficiency. Their value lies not in making complex judgments for you, but in standardizing the execution of repetitive operations under clear rules: select a batch of Excel files, uniformly convert them to the Csv format, and output them to a specified location.
Effect Preview: Changes from an xlsx Folder to a csv Folder
Let's first look at the file status before processing. In the screenshot, a folder contains multiple Excel files with the file extension .xlsx, indicating they are Excel workbooks. The file names cover common office data types, including Sales Data.xlsx, Project Tasks.xlsx, Product List.xlsx, Order Records.xlsx, Meeting Notes.xlsx, Feedback Survey.xlsx, Employee Salaries.xlsx, and Customer Information.xlsx.

If these files were to be saved as CSV individually, the similar operation would need to be repeated at least 8 times. If each file also requires confirming pop-up windows or selecting directories, the process would take even longer. The goal of batch processing is to complete the format conversion of these files in a single task.
After processing, the file extensions have been uniformly changed to .csv. You can see the result files: Sales Data.csv, Project Tasks.csv, Product List.csv, Order Records.csv, Meeting Notes.csv, Feedback Survey.csv, Employee Salaries.csv, and Customer Information.csv. The main parts of the file names remain unchanged; only the format is converted from Excel workbook to CSV file, which makes it very convenient for cross-referencing and verification with the original files.

This kind of processing result is suitable for subsequent system imports, platform uploads, reading by technical scripts, or archiving as standardized data files.
Operational Steps: Batch Saving as CSV with HeSoft Doc Batch Tool
Step 1: Open the Software and Enter Excel Tools
After launching HeSoft Doc Batch Tool , first observe the left navigation bar. The software organizes functions by file type and processing direction, including Home, Task Flow, All Tools, File Name, Folder Name, File Organizing, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, etc. Since this task involves processing Excel files, click "Excel Tools" on the left.
After entering Excel Tools, a group of Excel-related function cards will appear on the right. In the screenshot, you can see options like "Excel to JPG Image," "Excel to Docx," "Excel to PDF," "Excel to XPS," "Excel to Xls," "Excel to Xlsx," "Excel to Txt," "Excel to HTML Web Page," "Excel to Json," "Excel to XML," etc. The option we need to select is the 8th item, "Excel to Csv."

The operational goal of this step is to enter the correct batch conversion module. Selecting the wrong module might result in PDFs, images, or other formats. Therefore, before clicking, confirm that the card name is "Excel to Csv" and note its description: "Batch convert Excel files to Csv format."
Step 2: Enter the Conversion Page and Choose an Adding Method
After clicking "Excel to Csv," you will enter the task page for this function. The top left of the page shows "Return to Main Panel" and the current task name "Excel to Csv," indicating you have entered the correct function. The top right side has buttons like "Add File," "Import Files from Folder," "Clear," and "More."
If your Excel files are scattered in multiple directories, you can use "Add File" to add the xlsx or xls files you need to convert to the list. If the files are already concentrated in a single folder, it is more recommended to click "Import Files from Folder," which imports all files from that folder in one go, aligning better with the batch processing workflow.

In the screenshot, the red arrows point to "Add File" and "Import Files from Folder," indicating these are the key entry points for importing pending records. After the import is complete, the software will display the file information in the table list.
Step 3: Check Pending Records, Confirm No Missing or Incorrect Selections
After importing the files, the page is at Step 1 of the process: "Select records to process." The list displays the sequence number, name, path, extension, creation time, modification time, and actions. The screenshot shows 8 records in total, with a summary at the bottom showing "Record count: 8." This information helps users make a final confirmation before conversion.
It is recommended to focus on checking the following: Does the Name column contain all the desired Excel files for conversion, such as Customer Information.xlsx, Employee Salaries.xlsx, Feedback Survey.xlsx, etc.? Does the Path column point to the correct folder (the path in the screenshot is located in "Test folder 4" on the user's desktop on drive C)? Is the Extension column .xlsx or another Excel-related format? Does the record count match the expected number?
If you find a file that does not belong to this task, you can click the delete icon in the action column on the right side of that row. If the overall import is wrong, you can click "Clear" at the top and re-import. The biggest fear in batch tasks is an inaccurate input scope, so this step, though simple, can avoid subsequent rework.
Step 4: Click Next and Set the CSV Save Location
After confirming the pending records are correct, click the "Next" button at the bottom. The process bar on the interface shows that Step 2 is "Set save location." This indicates the software uses a wizard-style process: first select records, then set the output location, and finally start processing.
The setting of the save location will affect the convenience of finding the result files later. It is recommended to output the CSV files to a dedicated directory, such as "CSV Results," "Converted Files," or a project-designated import directory. This way, the original Excel files and the converted CSV files will not be mixed, making it convenient for both backing up source files and uploading the results to the system as a whole.
In batch Excel-to-CSV scenarios, the clearer the output directory, the more effortless the subsequent verification. Especially when the number of files is large, it is advisable not to save them arbitrarily in scattered locations on the desktop, but to create a specific, clear folder for the batch task.
Step 5: Proceed to Start Processing and Check Conversion Results
After setting the save location, continue following the software wizard into Step 3, "Start Processing." Once processing begins, the software will execute the conversion according to the records in the list, converting Excel files to the Csv format. After processing is complete, go to the save location to view the output results, confirm that the extension is .csv, and spot-check several files to see if they can be opened normally or recognized by the target system.
From the post-processing result image, you can see that the conversion results correspond one-to-one with the original file names, with the extension changed to .csv. For batch saving as CSV tasks, this is the expected outcome. Users do not need to open each Excel file individually to perform a "Save As" operation; instead, they complete the format unification of multiple files through a single task.
Common Questions and Notes
1. What is the difference between CSV and Excel files?
Excel files like xlsx and xls can save multiple worksheets, formulas, styles, filters, and complex formatting; CSV mainly stores text data, making it more suitable for data exchange. After conversion to CSV, files become more universal, but they should not be treated as a complete replacement for an Excel workbook. It is recommended to keep the source Excel files so you can trace back to the original data and formatting when needed.
2. Why organize the folder before batch conversion?
If unrelated Excel files are also placed in the same folder, using "Import Files from Folder" might add them to the task list together. Organizing the folder before conversion can reduce accidental processing. Checking the names and paths again via the list after importing provides a double layer of security.
3. Can the converted files be imported directly into the system?
Most systems supporting CSV import can read csv files, but different systems may have requirements regarding field order, header names, encoding, and date formats. Therefore, it is advisable to test with a small number of files first, and perform the batch import of all conversion results only after confirming correctness.
4. Will the file names change?
From the result images, the processed files retain the main body of the original file name; only the extension changes from .xlsx to .csv. This naming method makes it convenient for users to match source files with result files. However, in practical work, it is still recommended to check the output directory to confirm there is no overwriting of files with the same name or version confusion.
